Question

Which is a natural polymer:
a. Polythene
b. Cellulose
c. PVC
d. Teflon

Answer 1

Hint :In order to answer the question let us first know about polymers. A polymer is a natural or synthetic material that is made up of very large molecules called macromolecules that are multiples of smaller chemical units called monomers. Many of the materials used in living organisms are polymers, such as proteins, cellulose, and nucleic acids.

Complete Step By Step Answer:
Let us have a brief idea about Natural Polymer:
A polymer is made by combining small molecules or substances in a chemical reaction to form a single large molecule. Monomer refers to the small molecules that are used to make a polymer. purely natural Polymers are substances that can be found in nature. These polymers are made using the additional polymerization or condensation polymerization methods. Polymers can be found in abundance in nature.
Our bodies are made up of several natural polymers, such as nucleic acids and proteins. Cellulose is another natural polymer that is an essential structural component of plants. The majority of natural polymers are made from condensation polymers, and water is produced as a by-product of this process.
Cellulose: Cotton is the purest form of natural cellulose, as well as one of the world's most abundant organic compounds. cellulose is a key component of tree-based paper, as well as the supporting materials in leaves and plants. It's a polymer formed from glucose monomers, much like amylose.
Hence, from the above given data we can conclude that Cellulose is one of the natural polymers.
So, the correct option is: (b) Cellulose.

Note :
Proteins are the most common form of natural polymer found in almost all living things. Proteins are said to be the most flexible in nature. They have the potential to act as catalysts. Enzymes are proteins that aid in the breakdown of other proteins. Enzymes are responsible for a wide range of chemical reactions in our bodies, which happen a million times faster than they would without them. Haemoglobin is a protein contained in our blood that carries oxygen from the lungs to the human body's cells.
